研究了非马可夫环境中单量子比特逻辑门的性质,发现量子过程的非马可夫性有助于抑制环境产生的错误,更好地保护逻辑门的质量。同时也发现,当噪声逻辑门的操作时间略小于理想逻辑门所规定的时间时,逻辑操作的质量更好。
研究瞭非馬可伕環境中單量子比特邏輯門的性質,髮現量子過程的非馬可伕性有助于抑製環境產生的錯誤,更好地保護邏輯門的質量。同時也髮現,噹譟聲邏輯門的操作時間略小于理想邏輯門所規定的時間時,邏輯操作的質量更好。

The properties of single-qubit logic gates was studied under the effects of non-Markov environments. It was found out that the non-Markovianity of quantum process was beneficial for the suppression of mistakes induced by environments, so that improved the quality of logic operation; when the operation time of the noisy gate was slightly smaller than the one of the corresponding ideal gate, the accuracy of the logic gate was the best.
